COLLAPSIBLE TUBE Filed July 9, 1951 7 gwve'ntoc Eli Socolo/f q, JackJHZzu/Man' Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE Thisinvention relates to collapsible tubes, and has for its object toprovide, in a manner as hereinafter set forth, a tube of such classhaving as a permanent element thereof means whereby the expelling of thecontents of the tube is had by a rolling action of the tube body in lieuof a folding action.

'A further object of the invention is to provide, in a manner ashereinafter set forth, a collapsible tube so constructed and arranged toovercome the necessity of clamping to the open bot- I tom thereof aclosure therefor. I

A further object of the invention isto provide, in a manner ashereinafter set forth, a collapsi- 16 ble tube having a rolled endportion to provide for the closing of the bottom of the tube and furtherincluding as a permanent part thereof a roll coupled to and upon whichsuch end portion is coiled or rolled.

20 A further object of the invention is to provide,

in a manner as hereinafter set forth, a collapsible tube so constructedand arranged and having as a permanent part thereof means whereby theexpelling of the contents of the tube is had by a rolling. or coilingaction and further whereby the rolled or coiled part of the tube isprevented from unwinding or uncoiling.

A further object of the invention is to provide, in a manner ashereinafter set forth, a collapsible tube whereby the contents thereofare expelled by a rolling up action of the tube and with the coilsformed by such rolling up action automatically prevented .fromunwinding.

A further object of the invention is to provide,

85 in a manner as hereinafter set forth, a collapsible tube having as apermanent part thereof a cylindrical roll carrying a rolled up or coiledportion of the tube body for the purpose of closing the end or bottom ofthe latter.

40 Further objects of the invention are to provide, in a manner ashereinafter set forth, a collapsible tube for the purpose referred towhich is comparatively simple in its construction and arrangement,strong, durable, compact, thoroughly eflicient in its use, convenientlyoperated for the purpose of expelling the contents of the tube, readilyassembled, and comparatively inexpensive to manufacture;

With the foregoing and other objects in view,

combination and arrangement of parts as hereinafter more specificallydescribed, and illustrated in the accompanying drawing, wherein is shownan embodiment of theinvention, but it is to be understood that changes,variations and the invention consists of the novel construction,

modifications can be resorted to which fall within the scope of theclaims hereunto appended.

In the drawing wherein like reference characters denote correspondingparts throughout the several views:-

Figure 1 is a perspective view of a collapsible tube in accordance withthis invention.

Figure 2 is an elevation, partly in section of a collapsible tube inaccordance with this invention.

Figure 3 is a perspective view of the cylindrical roll carrying theretaining member for the coils of the rolled up portion of the tubebody.

Figure 4 is a view similar to Figure 3 with the retaining memberomitted.

Figure 5 is a View similar to Figure 3 of a modified form of rollcarrying a retaining member for the coils of the rolled up portion ofthe tube body.

Figure 6 is a view similar to Figure 5 illustrating the modified form ofroll with the retaining member omitted.

Figure 7 is a fragmentary view in elevation of the tube body.

The tube may be formed from paper, fabric, metal or a combination of thelatter and includes a container part 1, a breast part 2, a neck part 3,a tapered end portion 4, and the latter is coiled, as at 5 upon acylindrical roll 6 whereby the said tapered end portion 4 is closed.Mounted upon the neck part 3 is a re- 35 movable closure cap 7. Thelength of roll 6 corresponds to the diameter of the container part 1.The diameter of roll 6 may be as desired. The roll 6 is formed with alengthwise extending slot 9 for receiving the free end of the tapered 99end part or portion 4. Secured to one end of the roll 6 is a retainingmember 10 for the coils of the rolled part or portion 5 and said memberincludes a pair of arms 11, 12. The retaining member 10 is resilient.The arm 12 is of greater length than the arm 11, substantially of -bowshaped form and has its free end provided with a globular head 13. Thearm 11 opposes that end of the roll 6 to which the member 10 is attachedand the arm 12 is disposed lengthwise 100 of roll 6 and head 13 normallyseats upon roll 6, but when the part 4 is rolled upon roll 6 the head 13bears against the outer coil of such rolled part or portion 5 of thetube. The member 10 automatically functions to prevent the coils of theportion 5 from unwinding and further automatically acts to maintain suchcoils in position. The coiled part or portion 5 of the tube closes orseals the lower portion of the latter.

The form of roll shown in Figures 5 and 6 is the same as that shown inFigures 1, 2, 3 and 4, with this exception that in lieu of providing theroll, which is indicated at 14 in Figures 5 and 6 with a slot, it isformed with a lengthwise extending notch corresponding in length to thelength of the roll and indicated at 15 and the latter receives the freeend of part 4.

The slot 9, as well as the notch 15 provides means for connecting thetapered portion 4 of the tube to the rolls 6, 14 respectively. The formof fastening member employed in connection with the form shown inFigures 5 and 6 and which is indicated at 16 corresponds in constructionto the form of fastening member 10.

When it is desired to expel the contents of the tube "the-container part1 is wound or coiled about the coiled lower portion of the tube. Priorto the rolling up of the container part 1 from the rolled up or coiledportion of the tube the cap '7 is removed.

.Whatwe claim is:--

1. A collapsible tube having as a permanent part thereof a roll attachedto and upon which the bottom portion of the tube is coiled, and meanscarried by the roll for permanently maintaining the bottom portion ofthe tube rolled during the rolling of the latter and when in rolledposition.
